Abstract

Cloud Computing (CC) is coined as the paradigm shift of Information Technology (IT), as compared with the Packet Switching of Networking Technology. Experts in Communications and Networking fields recall remarkable changes that digital communications brought to the industry, academia, military, and thus our daily life. While discussions about Clouds and Grids are on the boiling points in the Cloudy community, this paper looks at the Clouds and Grids from networking standpoints as well as simulation opportunities that Cloud Networking (CN) provides. We look at some key issues like Quality of Services (QoS), Service Level Agreement (SLA), interoperability, migration between cloud networks, and network traffics. In addition, this paper compares clouds and grids and examines potential simulation needs.
